Steps to reproduce:
1. Open attached project "ShaderGraph.zip" and Scene "OutdoorsScene"
2. In Project window, select Assets -> ShaderGraph -> Experiment.mat
3. In Inspector window, adjust the "DissolveAmount" scale
4. Observe changes in Project window's "Experiment.mat" asset's preview, Inspector's preview
5. Compare to changes in Scene, Game view on the "Lamp_4" GameObject
Note: this is a shader authored with Shader Graph, using HDRP as the Active Target. The same applies to a shader created via RMB>Create>Shader Graph>HDRP>Lit Shader Graph. Since the Emission Weight property is not exposed, it is impossible to prevent Exposure from affecting the shader graph's emission.
Expected result: Both the material asset's previews, and the "Lamp_4" GameObject display a glow effect as the DissolveAmount scale is increased
Actual result: The material asset's previews display the effect correctly.
